Mullite insulation fire bricks are made from good quality and super pure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of production. Each grade of products has unique design to meet different thermal, physical and chemical demands, refractory brick .
· The product is sintered under high temperature with high— purity raw materials and advanced production technologies.
· High pressive strength.
· High temperature resistance as well as thermal shock resistance.
· It is widely used in the lining of medium-high temperature kilns.
Mullite insulation fire bricks refractory material can be used in linings or heat-insulating materials of the industries, such as ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc.
